Future and Ciara’s custody battle is playing out in the public, and it’s not pretty. On Monday (Jan. 4), the “Where Ya At” rapper blasted his ex on Twitter, claiming that she has prevented him from seeing their one-and-a-half-year-old son, Future.

“This bitch got control problems,” he tweeted, while revealing that he pays $15,000/month in child support.

But there are two sides to every story. Sources close to Ciara tell E! News that the singer has never stopped Future from seeing his son and that he does not and has not paid $15,000 in child support.

So why did Future go off? According to E!, he is jealous that Ciara has moved on (she is dating Seattle Seahawks quarterback Russell Wilson) and “that Future uses the situation to promote his music by staying in the press using her name.”

“Future has told her he hopes she fails in everything she does and that’s just being evil,” says the insider. “He is unable to move on and co-parent in a healthy way.”
